Be it known that l, LEXUS NV. HARDY, :i resident of Chicago, inthecounty ot Cook. and State of Illinois, have invented certain new anduseful improvements in Devices for Oiling Elevated Sheft-l'em'ings; sindl do hereby declare that thc following is zi. full, clear, sind exactdescription thereof, referencel being had to the accompanying drawings,and to the lett-ers of reference marked thereon, which form a partei1this speciiezition.

This invention rele-ii te Oilers for oiling` elevated allait-bearingsand the like; audit consists in the features and combinationshereinafter set forth. and pointed out in the appended claims.

Fig. 3 isa longitudine-l section Showing tire general invention Wanting certa-infeatures present iii Figs. 1 and 2.

The cylinder A is'proyided with a. iillinghole a stopped with eplug c.'at its upper end, tube C is provided with am opening c neer itsconnection with the pieton l), while itsupper cud is provided with ehoek In the simple construction shown in Fig. 3 the piston D fills the'cylinder A. The cylinder A. being filled with oilafnd the filling;Hhole stopped by the plug, the end of the hook C' on the tube C is thrustinto the cup of en elevated bearing and doWnwa-idpulling force islapplied to the handle B.

2. An oiler for elevated bearings and the like, comprising a receptacleand pump mounted on the end of a pole or handle, the pump piston beingconnected with a protruding, longitudinally movable delivery tube whichis provided with a hook adapted to be engaged with the cup or bearing tobe sup plied, whereby, tirst., the oiler may be raised to engagementwith the elevated bearing by the operator standing below, and, second,upon a downward pulling movement ot the pole or handle by the operator,the pump is operated. and the oil is expelled through the tube to thecup or bearing, substantially` as set 'foi-th.

3. In an oilerforelevated bearings, the coinbination of a receptacleclosed at both ends and provided at its lower end with means for itsattachment to a pole, a pump piston within the receptacle, and adelivery tube connected with the piston a nd prot ruding through the-upper end ot' the receptacle, said delivery tube being provided at itsdelivery end with a. hook adapted to be engaged with the cup or bearingto be supplied, whereby, the hook being so engaged, a downward pullingioree applied to the receptacle causes the piston to expel oil throughthe delivery tube to the bearing.

et. An oilervi'or elevated shaft bearings, the 5o combination ot aIreceptacle adapted to-be mounted on a pole, apump piston within thereceptacle, a delivery tube connected with the piston and protrudingthrough the upper end of the receptacle, said delivery tube ter- 5S Yininating in a hook-formed spout at its upper end, the extremity ofwhich is substantially in line with the straight portion of the tube,and a spring arranged to retract the delivery tubc, substantially as andfor the pur- 6o poses set forth. I

5. An oiler comprising a receptacle closed at both ends, a handlesecured to the receptaele, a separate piston pump secured within and ator near the bottom of the receptacle, a 65 delivery tube connectedwiththe pist-on of the pump and protruding through the top of thereceptacle, said tube terminating at its outer end in a hook-formedspout, and a spring for retracting the delivery tube.

Il. ln an oiler, the combination of a receptacle closed at both ends, anapertured diaphragm secured wit-hinthe receptacle and provided with adownwardly projecting plug having a lengthwise passage through it; ahol-7 5 low piston fitted to the plug and provided with a lateral openingwhich is covered by the plug except when the piston is retracted; adelivery tube connected with the bottom of the piston, said tube havingan opening witli- So 'in the piston, prttruding lthrough the plug andalso through the top of the receptacle, and having a hooleforined spoutat its upper end, and ay spring for retracting the piston and deliverytube., substantially as .de- 85 scribed and for the purposes setl forth.

In testimony that I claim the foregoing as my invention l a i'tix mysignature in presence of two witnesses.
